Answer:
x = 14
Step-by-step explanation:
The angles form a straight line which makes them add to 180 degrees
4x+ 8x+12 =180
Combine like terms
12x+12 =180
Subtract 12 from each side
12x+12-12 = 180-12
12x=168
Divide each side by 12
12x/12 =168/12
x =14
2(3t)=54
Divide both sides by 2
3t=27
Divide both by 3
t=9
You can plug it in 2(3*9) = 2(27) = 54
Answer:
width (C.I) ∠ width (P.I)
Step-by-step explanation:
In statistics, a confidence interval (C.I) is known as an interval estimate which is computed using the observed data that might contain the actual value of an unknown parameter. The confidence level is commonly used for estimation before examining the actual data. On the other hand, the prediction interval (P.I) is a range of values that calculate the value of a new observation by considering the existing model developed using the actual data. Therefore, the true statement is:
width (C.I) ∠ width (P.I)
Answer:
16.8 cm
Step-by-step explanation:
Volume = length x width x height
V = 4 x 3 x 1.4
V = 16.8
